How to reliably weld polypropylene pipes without a soldering iron

The popularity of polypropylene is growing exponentially every year, because the scope of its application is quite wide and very convenient.

It is not uncommon to use a special soldering iron in order to reliably connect two polypropylene pipes, but it is not always at hand.

In such cases, you can use a very effective method that my father always used.

Naturally, this will require some basic equipment and a little ingenuity and sleight of hand.

As a soldering iron, you can use either a turbo lighter or a gas cylinder with a torch. In my case, a balloon is used, since with its help the work goes much faster.

Now about the soldering technology itself.

Take a polypropylene corner and a smaller diameter tube.

Let's say we are faced with the task of soldering them. To do this, we turn on the gas burner and fix it on the table so that it is convenient to work.

I put the balloon on its side and put a metal strap to fix one position. which was the first to be at hand. We start to solder.

We take a corner and carefully start heating it from the inside, as shown in the photo above. It is necessary to heat until the inner diameter is slightly melted.

Next, we take the tube and heat it from the outside along the entire diameter. You also need to achieve a slight melting of the material.

And all that remains to do is insert the tube into the corner and wait until our connection cools down. Once the structure has cooled, it will firmly grab each other.

It is worth adding and warning that this method will never be suitable for water supply. The connection is certainly reliable, but over time it can weaken due to the pressure of water and a flood with financial losses is inevitable.
